Re: Has anyone hooked a flow meter to a pool with an Intelli
I actually have a digital flow meter installed on a dedicated long pipe after an intelliflow VS with a relatively new pool and large DE filter. All sorts of things impact efficiency of the pump, including how much inflow is coming from skimmers versus main drains, whether solar is active, and whether deep heating is going on, angles and sizes of various pipes, how much piping you have and how far the equipment is from the pool. In general, I try to keep gpm between 30-40pm as this is the minimum required to keep SWG, intellichem, solar, and heat pump happy.
Just general numbers:
Normal Minimal Energy Use Filtering Speed that keeps skimmer happy, 1650rpm, 32gpm, <300W
Solar Heating Speed (750 sqft of panels on double story house), 2300rpm, 38gpm, ~710w (treated as the high filtering speed each day to ensure pool surface is cleaned of leaves/etc).
Backup Heating via heat pump(rarely active), 2000rpm, I haven't checked gpm for this in awhile but I think it was around 37-39gpm, don't remember watts.
Pump is on for 12hrs/day, 7hrs solar and 5hrs filtering. The long runtime is mostly to accommodate the intellichem and that we mostly swim in the evening while the pump has to run during the day to get cheap heating via solar.
